so i guess its a "wont" instead of "cant" when talking about online vendors?

Some vendors just want to play "CYA" to be safe. If those vendors are willing to pass up perfectly legal sales to placate their fears, then that's their choice. Take a look at "Sportsman's Guide" - they are so scared they won't even ship a wrench (for an AR-15 barrel) to this "state".

There are plenty of ammo dealers who are willing to make legal sales, and I go out of my way to support them. I buy ALL of my ammo outside the City of Sacramento because I don't want to deal with needless paperwork and I also want to deprive the city of the taxes they would have collected. I look at it as "voting with my wallet".
